Challengers of the Unknown by Jeph Loeb and Tim Sale

More about the book

"Time has finally caught up with the Challengers of the Unknown. The world seems to have passed them by, and they are now relics, curious artifacts and faded celebrities. All that changes when their fabled mountaintop headquarters blows up and the quartet suddenly find themselves on trial for their lives. So begins the most audacious case of their careers. This graphic novel is the first creative pairing of writer Jeph Loeb and artist Tim Sale, whose highly regarded partnership would give way to legendary works including BATMAN: THE LONG HALLOWEEN, SUPERMAN: FOR ALL SEASONS and CATWOMAN: WHEN IN ROME."-- Provided by publisher
